Estimioo
3.8Free planning poker, retrospectives and standups for Scrum teams
Estimioo is a lightweight, browser-based agile-ceremony tool that bundles AI-assisted planning poker, a template-driven sprint retrospective board and async daily standups into one shared workspace. The product's centre of gravity is estimation, but the retro module has grown since launch: the vendor now lists a library of retrospective formats (Start/Stop/Continue, Sailboat, Mad/Sad/Glad, 4Ls, Starfish, Sprint Timeline and more) rather than a single fixed board. It's still a reflection-and-summary tool, not a deep facilitation suite with dot voting, grouping and owned action items.

NimbleRetro
3.0Time-boxed retros with 5-Why root cause analysis
NimbleRetro is the retrospective module inside NimbleWork's broader Nimble agile platform. It runs structured, time-bound retros through Icebreaker, Ideation, Grouping, Voting, and Root Cause Analysis stages, with anonymous input, action item tracking, and a 5-Why root cause workflow. Native iOS and Android apps complement the web product, and action items convert directly into Nimble workitems (user stories and cards).
Full review →Summary
Estimioo scores 3.8 overall and is best for small, distributed Scrum teams who mainly want fast, AI-assisted planning poker and async standups, and want a template-driven reflection board for retros rather than a full facilitation suite with voting, grouping and owned action items. It offers a free tier.
NimbleRetro scores 3.0 overall and is best for small agile teams that want a no-frills retro with built-in root cause analysis and a mobile companion app, especially teams already using the wider NimbleWork (SwiftKanban / Nimble) suite. It offers paid plans from ~$7/user/mo (est.).
Estimioo leads on ease of use, value, fun factor and AI & insights. NimbleRetro leads on retro toolkit, open platform and enterprise-grade.

Estimioo — pros
- + Genuinely cheap — flat $7/workspace/mo Team plan (not per-seat) and a usable free tier
- + Fast, no-friction planning poker with multiple scales and hidden-until-reveal voting
- + AI story-point suggestions and estimation-accuracy tracking, powered by Claude with zero data retention
- + Guests join without signup via link or QR code — low overhead for distributed teams
- + Three ceremonies (poker, retro, standup) in one shared workspace
Estimioo — cons
- − Retro board is reflection-and-summary only — no dot voting, grouping, anonymity, phase timer or action items with owners and carry-over, even with the expanded template library
- − Verified AI is estimation-focused; the advertised Claude retro summaries (mood, themes, action items) couldn't be verified hands-on
- − No Slack/Teams, Confluence, GitHub, Linear or Azure DevOps integrations; Jira is a paste-URL preview for poker only
- − No SSO, SOC 2, audit logs or published data-residency — not built for enterprise procurement
- − Free sessions expire after 1 hour and cap at 5/month; no recurring retros or persistent retro history
NimbleRetro — pros
- + Structured 5-Why root cause workflow built into the retro flow
- + Anonymous input and time-bound stages keep retros focused
- + Native iOS and Android apps for mobile participation
- + GDPR compliant; sits under NimbleWork's ISO 27001 / SOC umbrella at the platform level
NimbleRetro — cons
- − Only four templates, with stage flexibility limited to column count
- − No SSO/SAML, SCIM, or SOC 2 Type 2 attestation specific to the retro product
- − Vendor now markets 'Generative AI' but no concrete retro AI (clustering, summaries, sentiment) is documented — treat as unverified
- − Thin direct-integration story for the agile stack — no documented Jira, GitHub, Linear, or Azure DevOps hooks for the retro module
- − Participants are limited to members of the Nimble project the retro is created from
- − Pricing not transparently published; demo-gated (third parties peg it around $8/user/mo)
